Design Reference

API Roadmap Phase 1: Implement Refresh Rotation and Logout API.

Dependencies

• Blocked by: Feature: Add Auth Token and Session Persistence Models; Feature: Standardize API Contracts Pagination and Versioning
• Blocks: Feature: Expose Session and Device Management API; Feature: Harden Authentication and Account Security Policy

Tasks

• Issue short-lived access and opaque refresh tokens at login
• Rotate refresh token atomically with family linkage
• Detect rotated-token reuse and revoke the family
• Add logout current and logout all sessions
• Document cookie/header transport and CSRF policy
• Test races, replay, expiry, revocation, and logout

Acceptance Criteria

• Refresh rotates once per valid use
• Replay triggers documented family revocation
• Logout prevents targeted refresh
• Transport is documented and tested
• OpenAPI passes

Verification Evidence

• Attach redacted login/refresh/logout curl and replay tests
